It must have taken a mountain of make-up remover to shed her Halloween 'alien transformer' persona.

But when Heidi Klum hit the red carpet on Monday evening to attend a charity event, she was fresh-faced and looking fabulous.

Twenty-four hours after she and husband Seal stepped out in jaw-dropping ensembles for their annual Halloween party, the model mum went for a completely contrasting look in a nude dress and barely-there make-up.

The 37-year-old and her musician spouse were co-hosting the Worldwide Orphans Foundation annual benefit gala, held in downtown Manhattan.

As parents to four children, Heidi and London-born Seal, 47, are keen supporters of the cause.

While at the event, they also addressed the audience, which included Hugh Jackman and his wife Deborra-Lee Furness.
